How to Legally Reduce Your Tax Bill in Australia: 10 Strategies for 2026

Strategy 1: Salary Sacrifice Into Superannuation

Salary sacrifice is the most powerful tax reduction tool available to Australian employees. Instead of receiving part of your salary as cash — which is taxed at your marginal rate of up to 47% — you divert it to your super fund, where it is taxed at just 15%.

For someone earning $120,000, the marginal rate (including Medicare levy) is 39%. Salary sacrificing $10,000 saves 39% − 15% = 24% = $2,400 in tax. Sacrificing $20,000 (within the $30,000 concessional cap, less employer contributions of roughly $13,200 at 11%) saves a similar proportion. The money is not lost — it builds your retirement nest egg.

To salary sacrifice, ask your employer to amend your package. The arrangement must be set up prospectively (before the work is performed) and documented in writing. Concessional contributions above $30,000 per year attract a 32% excess contributions charge, so check your employer SG contribution level first.

Estimated annual saving: $1,500 – $5,000+ depending on income and amount sacrificed.

Strategy 2: Claim All Work-Related Deductions

The ATO allows deductions for expenses you incur in earning your income, provided they are not private, domestic, or capital in nature. Many employees claim far less than they are entitled to. Claimable work expenses include:

• Tools and equipment specific to your role (tradesperson's tools, nurse's uniform, safety gear)
• Professional association memberships and subscriptions (CPA, AHPRA, Law Society fees)
• Technical journals and industry publications directly relevant to your work
• Self-education expenses directly connected to your current employment (not a new career)
• Work-related travel (not commuting from home to a regular workplace)
• Protective clothing required by your employer (not conventional work attire)
• Laundry of work-specific uniforms (up to $150 without receipts if below certain thresholds)

The rule is: you must have spent the money, you must have not been reimbursed, and it must be directly related to earning your income. Keep receipts and a log. At $100,000 income, every $1,000 in legitimate deductions saves $345 in tax.

Estimated annual saving: $300 – $2,000 depending on occupation.

Strategy 3: Claim Working-From-Home Deductions

If you worked from home during 2026-27, you can claim the ATO's fixed rate of 67 cents per hour for each hour worked from home. This covers electricity, gas, internet, phone, and stationery — no receipts needed for those components, but you must keep an actual log of hours.

An employee working from home 3 days per week for 48 weeks (a realistic hybrid arrangement) logs 3 × 8 × 48 = 1,152 hours. At 67 cents, the deduction is $772. At 32.5% marginal rate, the tax saving is $251. If you also claim depreciation on a laptop, desk, and chair purchased for home work, the total deduction rises substantially.

The actual cost method is more complex but may yield a higher deduction if you have a large, dedicated home office, high electricity bills, or expensive equipment. Under the actual cost method, you calculate the real cost of each expense attributable to work use.

Estimated annual saving: $200 – $600+ for typical hybrid workers.

Strategy 4: Claim Investment Property Deductions in Full

If you own a rental property, the ATO allows deduction of all genuinely incurred costs of producing rental income. Investors frequently miss or underestimate these categories:

• Loan interest (the single largest deduction for most investors)
• Council rates and water rates
• Landlord insurance and building insurance
• Property management fees (typically 7–10% of rent)
• Repairs and maintenance (not capital improvements — those are added to cost base)
• Depreciation of plant and equipment (oven, carpet, hot water system)
• Capital works deduction — 2.5% per year on the construction cost of buildings built after September 1987
• Advertising for tenants, lease renewal costs, body corporate fees
• Accounting and tax agent fees for the property portion of your return

A depreciation schedule from a quantity surveyor typically costs $500–$700 but can unlock $3,000–$8,000 in annual depreciation deductions on newer properties.

Estimated annual saving: $2,000 – $10,000+ depending on property and borrowing level.

Strategy 5: Negative Gear an Investment Property or Shares

Negative gearing occurs when the cost of holding an investment exceeds the income it generates. The ATO allows this net loss to be deducted against other income, such as salary. This is covered in detail in our negative gearing guide, but the core mechanic is: a $12,000 annual rental shortfall at a 39% marginal rate saves $4,680 in tax.

Negative gearing applies to shares as well as property — if you borrow to invest in a share portfolio and the dividends do not cover the interest, the shortfall is deductible. This is a legitimate strategy, though it requires the investment to generate capital growth to break even economically.

Estimated annual saving: $3,000 – $8,000 for typical negatively geared property investors in higher brackets.

Strategy 6: Prepay Investment Loan Interest Before 30 June

Individuals (not companies or trusts) can prepay up to 12 months of investment loan interest before 30 June and claim the deduction in the current financial year, even though the interest period extends into the next year. This brings forward a tax deduction from a future year into the current year.

If your investment loan has $30,000 of interest for the year and you prepay the July–June instalment in late June, you claim $30,000 this year instead of next year. You do not permanently save tax, but you defer it — and the time value of money makes earlier deductions more valuable.

This strategy works best at the end of a higher-income year, or when you expect your income to drop (e.g., parental leave) in the following year. Lenders must agree to accept prepayment — most investment loan products allow it, but check your loan terms first.

Estimated benefit: Defer $3,000–$12,000 of tax by 12 months.

Strategy 7: Donate to Deductible Gift Recipients (DGRs)

Donations of $2 or more to ATO-endorsed Deductible Gift Recipients (DGRs) — registered charities, universities, certain cultural organisations — are fully deductible. You must have a receipt. The donation is deducted from your taxable income, not offset against your tax.

A $500 donation to a DGR charity at a 39% marginal rate costs you $305 after tax. The charity receives $500. Non-DGR donations (e.g., to a crowdfunding campaign, a foreign charity not registered as a DGR) are not deductible. Always check the ATO's ABN Lookup to confirm DGR status before donating and expecting a deduction.

Estimated saving: Marginal rate applied to total annual donations.

Strategy 8: Take Out Private Health Insurance to Avoid the Medicare Levy Surcharge

If your income exceeds $93,000 (single) or $186,000 (family) and you do not hold a complying private hospital cover policy, you pay the Medicare Levy Surcharge of 1% to 1.5% on your total income. At $100,000, that is $1,000 per year. At $145,000, it is $2,175.

Basic private hospital cover can cost as little as $1,000–$1,500 per year for a healthy individual in their 30s. If the MLS you would otherwise pay exceeds the cost of cover, the insurance effectively pays for itself — and you also have the health cover as a benefit.

Additionally, people over 31 who do not have private hospital cover accumulate a Lifetime Health Cover (LHC) loading of 2% per year — meaning cover taken out at 40 costs 20% more than cover taken out at 31. Taking cover earlier locks in the base rate.

Estimated saving: $950 – $2,175 per year in MLS avoidance at relevant income levels.

Strategy 9: Make Spouse Super Contributions for a Tax Offset

If your spouse earns less than $40,000, you can make after-tax contributions to their super fund and claim a tax offset of 18% on contributions up to $3,000. The maximum offset is $540 per year ($3,000 × 18%). The offset phases out as the spouse's income rises from $37,000 to $40,000.

This strategy does two things: it reduces the super gap between spouses (important for retirement equity, particularly for partners who took time off to raise children) and it gives the contributing spouse an immediate 18 cents per dollar tax benefit. The $3,000 contributed also remains in super, compounding in a tax-preferred environment.

At $3,000 contribution, the net cost after the offset is $2,460, and the spouse's super grows by $2,550 (after the 15% contributions tax inside the fund). That is a better after-tax return than most savings accounts.

Estimated saving: Up to $540 per year.

Strategy 10: Tax Loss Harvesting on Shares

If you hold shares or other investments at a capital loss, you can sell them before 30 June to crystallise the loss, which can then be used to offset capital gains in the same year or carried forward to offset future gains. Capital losses cannot be used against ordinary income — only against capital gains.

For example, if you have a $20,000 capital gain from selling a property and a $15,000 capital loss in your share portfolio, selling the losing shares before 30 June reduces your net capital gain to $5,000 (which, after the 50% discount if held 12 months, adds only $2,500 to your income). Tax saving at 32.5% rate: $4,875 on the original $15,000 loss.

Be aware of the wash sale rule: the ATO may disallow a loss if you sell an asset solely to crystalise a loss and immediately repurchase the same or substantially identical asset. The intent must be genuine, and there should be a meaningful interval between the sale and any repurchase.

Estimated saving: Highly variable — can save thousands if timed against a capital gains event.

Summary: Tax Saving Potential at a Glance

Frequently Asked Questions

Is salary sacrifice legal and safe?

Yes. Salary sacrifice into super is a legitimate ATO-endorsed tax strategy used by millions of Australians. It is governed by the Superannuation Industry (Supervision) Act and the Income Tax Assessment Act. The only risk is that contributions above the $30,000 concessional cap are taxed at an additional 32%, so always check your employer SG level before sacrificing.

Can I claim tax deductions if I work from home only occasionally?

Yes, but only for the hours you actually worked from home. You cannot claim a full year of WFH deductions if you only worked from home for part of the year. The ATO requires a genuine record of actual hours — a rough estimate is not sufficient under the current 67 cents per hour method.

Can I reduce my tax by putting money into an investment bond or education bond?

Investment bonds (also called insurance bonds or education bonds) compound earnings internally at the 30% corporate tax rate, and if held for 10 years, any proceeds on redemption are tax-free in the hands of the investor. They can be useful for people in high brackets who have maxed other options, but they are illiquid and should be considered as a medium-to-long-term vehicle.

What happens if the ATO audits my deductions?

The ATO will ask you to substantiate your claims with evidence — receipts, bank statements, a work diary, or employer confirmation. If you cannot prove a deduction, it will be disallowed and you may face a shortfall penalty (10–50% of the unpaid tax) plus interest. Keeping organised records throughout the year is far easier than reconstructing them later.
